BOBBIN-SUBPORT FOR CREEL-FR-AMES.

Patented Apr. 11, 1916.v

Application led July 30, V1915. Serial No. 42,779.

To all whom it may concern:

v Beit known that I, JOI-IN W. KIRKUS, a citizen of the United States, residing at East Tallassee, in the county of Tallapoosa and Y State of Alabama, have invented'new and useful Improvements, in Bobbin Supports for Creel-Frames, of which the following is a specification.

This invention relates to bobbin supports for creel frames, and one of its objects is to provide a bobbin support which is simple of construction, admits of the ready, quick and convenient application and removal of the bobbin, and permits the bobbin to have free and easy rotation in the operation of unwinding the roving.

A further object of the invention is to pro' vide a bearing support for the lower end of the bobbin, which comprises a bearing member detachably held in position upon the lower creel bar and which is frictionally engaged by the bobbin, said bearing member having bearing in a stepped bearing block disposed within a cavity in the lower creel bar, by means of which a lower bearing support is provided which is of maximum durability and yet may be readily removed for the substitution of a new bearing member when occasion requires.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing in which Figure 1 is an elevational view showing a portion of a creel frame with a pair of bob bins held in position therein. Fig. 2 is a vertical section through the same. Fig. 3 is a sectional plan view showing one of the bottom bearings and one of the bearing cavities or sockets.

Referring to the drawing, 1 designates the upper creel bar'and 2 the lower creel bar of the creel frame of a spinning or other analogous machine, which frame supports bobbins 3, of which any number may 'be employed. These bobbins hold the rovings which are to be spun, and are revolubly mounted for the free unwinding of the rovings therefrom in the operation of the machine.

The upper end of each bobbin is formed with a bearing recess 4 to receive a headed bearing pin or stud 5 depending from the upper creel bar 1, said recess being of greater length or depth than the stud to permit the bobbin to have a certain degree of vertical sliding motion in applying and removing it, as hereinafter fully described.

The lower end of the bobbin is formed with a recess 6to receive and fit over a block or head 7 provided with a conical bearing member 8, which is revolubly mounted within a recessed bearing cavity or socket 9 in a bearing socket V9, whereby the bobbin is revolubly mounted in position between the two bars of the creel frame. The recesses t and 6 may constitute the upper and lower terminals of a continuous bore or passage through the bobbin, as shown.

The head 7 of the bearing member carries Va circular retaining disk 10, which is -arranged to turn in a recess or depression 11 in the upper face of the bar 2. This disk is arranged beneath the overhanging end portions 12 of cooperating pivoted fastening members or turn-buttons 13, pivoted to the creel bar 2, as shown at 14. These pivoted fastening members are adapted to be swung into and out of retaining position with re spect to the retaining disk, and thus serveas latches to hold the bearing member against upward movement or displacement, and which are movable out of the path of the disk to permit of the removal of the bearing member for renewal, repairs or other purposes. Preferably the pivoted fastenings 13 are pivotally mounted at points centrally between their ends and between adjacent retaining disks of bobbin supporting members, so that the opposite ends of a fastening member may coperate with and retain inV position two adjacent bearing members, as shown. The bobbin may, however, be applied and removed by a combined pivotal and longitudinal sliding motion on the headby dotted lines in.Fig. 2.

It will be evident from the foregoing de- A scription, taken in connection with the drawing, that the construction described provides a bobbin support which is simple of construction, permits of the convenient application and removal of the bobbin, adapts the soV Y ed stud 5 and bearing head 7, as indicated l I claim l. In a bobbin support for creel frames, the combination7 with upper and lower creel bars, the upper creel bar being provided with a supporting projection and the lower 'c1-eel bar with a bearing socket and a recess of greater diameter than said socket and communicating with the upper portion thereof7 of a bearing block within the socket, a bearing member having a conical portion engaging said block, a horizontal disk carried by said bearing member and movable within said recess, a bobbin slidably and pivotally connected with the projection of the upper creel bar and formed with a socket at its lower end receiving said bearing member, and means upon the lower creel bar arranged to engage the disk to hold the disk and bearing member against displacement.

2. In a bobbin support for creel frames, the combination of an upper creel bar provided with a series of spaced projections, a

lower creel bar having sockets therein, stationary bearing members arranged within the sockets of 'the lower creel bar, rotary 25 bearing members engaging said stationary bearing members, bobbins slidably and pivotally engaging the projections of the upper Creel bar, and provided with sockets at their lower ends receiving and detachably 3o arranged to project over the disks of adjar cent bobbins and to hold the same 'from dis placement. y

In testimony whereof I aiix my signature in presence of two witnesses.
